Last week I , and severalothers , wrote about the extraordinary and unfounded conclusions published in a JACS perspective, that dinosaurs may have evolved into intelligent life elsewhere in the universe.

Well it gets worse, because as Stuart Cantrill (editor of Nature Chemistry) pointed out on twitter (@stuartcantrill), this isn’t the first time Prof Breslow has made these claims. Nor in fact is it the first time he’s published this article. It also appeared in the Israel Journal of Chemistry last year. Huge chunks of the JACS article are copied verbatium from the IJC review.

Here’s Stuart’s analysis of the JACS article, he’s highlighted the bits that appear in the IJC review. The subsequent pages are covered with just as much highlighterpen.

I wonder if JACS’s has a policy on self plagiarism?

EDIT: Here’s the self-plagiarised sections from the remainder of the paper.

“Authors should not engage in self-plagiarism (also known as duplicate publication) – unacceptably close replication of the author’s own previously published text or results without acknowledgement of the source. ACS applies a “reasonable person” standard when deciding whether a submission constitutes self-plagiarism/duplicate publication. If one or two identical sentences previously published by an author appear in a subsequent work by the same author, this is unlikely to be regarded as duplicate publication. Material quoted verbatim from the author’s previously published work must be placed in quotation marks. In contrast, it is unacceptable for an author to include significant verbatim or near-verbatim portions of his/her own work, or to depict his/her previously published results or methodology as new, without acknowledging the source.”

I write for http://www.chemistry-blog.com and I would very much like to share your comments on this issue with my readers. We are particularly keen to hear why Prof. Breslow appears to have been exempt from your ethical guidelines.

UPDATE 26/04 – In a statement, the ACS says, “We are following established procedure to investigate the claim of self-plagiarism. If it is determined that this is case of self-plagiarism, appropriate action will be taken as provided for in our ethical guidelines.”
